The use of SCMs played an important role for the canister storage facility at the Hanford Site nuclear facility. The CSB is a large, 42,000 square foot facility in Hanford’s 200 East Area which stores about 2300 tons of spent nuclear fuel packaged in approximately 400 Multi-Canister Overpacks (MCO’s). The MCO’s are stored in 220 carbon steel tubes within a below grade concrete vault. The MCO’s will be safely stored in the tubes until permanent placement in a National Repository.  

This 5200 ft² (483 m²) parking deck (Fig. 1) was nearing the end of its service life, and was characterized by widespread concrete deterioration and severe corrosion of reinforcing and prestressing steel. As an alternative to demolition and reconstruction, the owner was able to repair the structure, reducing environmental impact while providing significant initial cost savings, life-cycle cost savings, and schedule savings.

When a wooden floating dock in the Port of San Diego, San Diego, CA, had deteriorated to the point of having to be torn down, the owners chose to replace it with a floating dock assembled from precast concrete modules, the durability offered by the precast dock was a key consideration, and the modular design allowed a few standard-sized sections to be used in the creation of a variety of configurations.

Through the use of concrete repair procedures recommended by the International Concrete Repair Institute (ICRI) (chloride extraction and galvanic protection), a 50-year service life extension to this 75-year-old structure was designed and implemented. Designed and built in the 1930s as a Depression-era work project, the Rainbow Bridge is a critical transportation link in the Cascade Mountains north of Boise, ID. Completion of this project kept 1809 yd3 (1383 m3) of concrete in service.

American Engineering Testing Inc. (St. Paul, MN) used the design and construction of a new X-ray vault to reduce a concrete mixture’s carbon footprint and the potential for a reduction of virgin material. The vault is entirely concrete, with a plan section of 30 x 20 ft (9.1 x 6.1 m), 12 ft high (3.7 m), and 3 ft (1 m) thick walls. The target strength was 4000 psi (27.6 MPa) at 56 days.

When the City of Leawood, Kansas, implemented new regulations requiring developers to address stormwater runoff for the health of the community, local officials knew that their own construction practices would reflect the expected and required policies in the community.
